Order of operations
PEMDAS
parethasees (inner to outer)
exponents
multiplication and division
addition and subtraction
remember thah yuo do all these left to right

so


[7-(2-5(4-2)+7)]+2
inner to outer
4-2=2

now we have
[7-(2-5(2)+7)]+2
multiply since no further parnthasees
2*5=10

now we have
[7-(2-10+7)]+2
add or subtract (subtraction is addition of a negative)
2-10=-8, and -8+7=-1

now we have
[7-(-1)]+2
last parenthsees/brackets
remember that subtracting a negative is the same as adding a positive
7-(-1)=7+1=8

now we have
[8]+2
add
10


yep, 10 is right
